Speccation of Letters Patent.

Patented Apr. 7, 1914.

Application led May-22, 1,912. Serial No. 698,925.

T0 all whom t may concern:

Be it known that I, WILLIAM J. FLnnrNc, J r., a citizen of the United States, residing at Darien, 1n the county of Fairfield and State of Connecticut, have invented certain new and useful Improvements i-n Car-Ventilators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in ventilators for cars and embodies the generic principles of the injector and ejector type such as is shown and described in Letters Patent No. 793,403, and No. 830,749, to Ross Taylor, assignor to the Automatic Ventilator Company My present invention has for its object the utilization of the principle of operation of such devices and by modification and arrangement to apply the same to the modern car construction, known in the art as archedroof cars.

My invention has also for an object to utilize the interior anti-draft air distributer, as a support for the car lighting lamps.

With these and other objects in view, my invention consists in the construction and arrangement hereinafter, and in detail more fully set forth.

In order that those skilled in the art to which my invention appertains may know how to make and fully understand my invention, I will proceed to describe the same referring by numerals to the accompanying drawings in which,

Figure 1, is a front elevation showing my improved Ventilating devices applied to the arch roof of a car, the roof being shown in broken lines. Fig. 2, is side elevation. Fig. 3, is a horizontal, longitudinal, sectional view on line A-B of Fig. 4. Fig. 4 is a bottom plan view with a dust-cap removed, and Fig. 5, is a perspective view of the dust cap.

Similar reference numerals indicate like parts in the several figures of the drawing.

1, represents in broken lines the car roof in and upon which is mounted a hood, 2 having conical or beveled top 3, adapted to shed water and moisture. The hoodV 2, which is preferably cylindrical in cross-section passes through an opening in the car roof 1, and is secured thereto by a metal ring 4, located upon the outer surface of the roof, and a similar ring 5, located against the inner surface of the roof, the two rings secured iixedly in place by suitable screw bolts and nuts (3 (see Fig. 3). The hood 2, is provided with transverse, diametric partitions 7 which extend a suitable distance below the lower terminus of the wall of lthe hood as clearly shown in Fig. 3. The

quadrant spaces between these partitions are closed at the top by curved or arch-shaped closures 8, which deflect the incoming air currents and lead them downward as will be more fully explained hereinafter.

9, is a deflecting disk which is provided with transverse ribs 10 (see Fig. 5), which may constitute continuations of the partitions 7 and are held in alinement therewith by suitable embrasures 11 (see Fig. 3), and the deiiecting disk when adjusted, is held in position by a suitable screw 12, threaded into a female threaded socket 13, at the junction of the partitions 7.

' On the outside of the outer extension of the wall of the hood 2, and opposite each other are secured exterior defiectors 14, each of which is arranged between openings in the wall of the hood, which openings are provided with interior louvers 15, as clearly shown in Figs. 2 and 3, which are inclined upwardly as shown in Fig. 3, and lead the incoming currents of air toward the curved or arch-shaped closures of the quadrant spaces between the partition 7, and to similarly lead the out going currents of vitiated air as they reach the curved or arch-shaped closures in an obvious manner.

The construction of the exterior deflectors 14, is most clearly shown at Fig. 4, but constitutes no part of my invention.

The roof 3 of the hood 2 is formed with eaves extending a suitable distance over the vertical wall of the hood and may be strengthened and made rigid by an ordinary rolled bead 1G. The outside ring 4, surrounding the wall of the hood 2, and also the inner ring 5, may have a water proof packing arranged between them, and the roof of the car to avoid the possibility of moisture entering the car. The louvers may be either fixed as shown, or they may be adapted for adjustment at varying angles, this, however, 1 do not claim as of my invention, as such construction is shown in the prior art.

The deflecting disk 9, is adapted to catch CTI when so used saves room which otherwise' would be necessary in the ceiling of the car.

Having described the construction and arrangement of my improved ventilator devices, I will now describe the operation: As the car is moving againsttlie air, the latter impinges upon the forward side of the outside delectors 14, and it is directed into the car thro-ugh the louvers l5, in front of the deiiectorgin passing through the inclined louvers it is led in the direction indicated by the .arrows shown in Fig. 3, and escapes at the periphery of the deflecting disk 9, to the interior of the car, while the vitiated air in the car which naturally rises toward the ceiling, is exhausted through the quadrant spaces and louvers in rear of the outside deflector 14, at which locality a vacuum is produced by the movement of the car. WVhen the movement of the car is reversed, naturally a reversed action of the air currents ensues.

It will be understood that from the construction and arrangement shown and described, that the fresh air is introduced, and the vitiated air exhausted in such manner as not to induce to any perceptible and disagreeable degree drafts within the car.

l/Vhile the devices shown and described are especially designed for use with the well Copies of this patent may be obtained for ve cents each, by addressing the known arch-roof cars, it will of course be understood that they may, with equal facility be applied on the top and center of the ordinary monitor roof cars.

The devices are simple and economical of construction and readily applied.

What I claim as new and desire to secure by Letters Patent is:

l. In combination with the dome-roof of a car', a hood passing through said roof and secured in position therein, and having louyered openings on either side above the car roof, the interior divided by transverse partitions into quadrant spaces leading to th-e interior of the car; exterior reversely inclined dellectors between the louvered openings, and a deflecting cup-shaped shield, lo-

cated at the termini o-f the quadrant spacesV and with air space between the quadrant spaces and said shield, whereby the fresh air may be delivered to the interior ofthe car and the vitiated air ejected therefrom, as hereinbefore set forth.

2. In combination with a'dome-roofed car, a hood provided with quadrant air spaces, having arch-shaped closures at the upper end, louvered openings in the opposite sides of the hood with projecting outside defiectors between each pair of quadrant air spaces; and a cup-shaped shield at the lower eX- tremities of the air spaces substantially as sho-wn and described.

In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
